Abstract
To prevent seal failure in internal combustion engines, blow-by gasses leaking past the piston rings require venting. However, moving engine components cause airborne oil particles to be mixed in with the gasses. Depending on breather system and engine type, oil carry-over can cause increased operating costs, reduced engine performance and emissions issues. The present invention provides a simple and inexpensive barrier device fitted in a cylinder block. The device is positioned such that oil particles impact on the device and coagulate to form droplets which subsequently run back to the crankcase. Some advantages provided by the present invention are that the engine envelope is unaffected, the barrier device is the only additional part, and the cylinder block requires no or minimal adaptation.
